No, we definitely should not drive other species to extinction. That is unethical.
However, rendering ourselves unavailable as prey or inhospitable as hosts/reservoirs is ethical. If a species goes extinct because it can no longer infect or survive in our bodies, that is the natural consequence of evolution. This scenario is very different from genetically altering inconvenient species or hunting them to total eradication.
If the ends are to be met and are the same, it is better to reach them through ethical courses of action.
